Scientists stunned by children's lung recovery in ultra low emission zone
Summary
Scientists studied over 3,400 children in London and Luton and found that lung growth in London children improved quickly after the Ultra Low Emission Zone (Ulez) was introduced in 2019. The research shows that reducing air pollution helped reverse damage to children's lungs, allowing them to catch up with children in less polluted areas.Key Facts
- The study tracked children aged 6 to 9 in London’s Ulez and compared them to children in Luton for five years.
- London children’s lung capacity was smaller than Luton children’s before Ulez but caught up after four years.
- The Ulez reduced harmful pollution like nitrogen dioxide from motor vehicles in London.
- The percentage of London children with lung impairment dropped from 14% to 9% during the study.
- Lung function tests showed children could breathe more air out quickly, indicating better lung health.
- Children’s lungs are vulnerable to pollution because they are still developing and are closer to exhaust fumes when outside.
- Air pollution can cause asthma, heart disease, diabetes, and early death.
- The study provides strong evidence that clean air zones can help improve children’s lung health.
